Brake wire slack

How much slack should you have in the wires going to the brakes on the trailer? After doing the axle flip/EZFlex and still on jack stands I have some slack but don't know how to test to see if it's enough when traversing uneven terrain. On the rear axle I pivoted the EZ flex backwards and front spring eye up and it has a little bit of slack but not a lot. You can move the wires a little bit.

You need to allow enough slack so that the wires no not get damaged when turning or when traversing uneven terrain.
(A "little bit" may or may not not be enough).
Because every situation is different only you can determine how much slack is necessary in your particular situation.

Brake wire slack

Your trailer is going to swing a maximum of 90 degrees on each side of the ball. Measure from your TV electrical connector to the center of the ball. Measure from the center of the ball to where the cable is attached to the trailer tongue. Add them together. I'd want my cable to be minimum of that length plus 6-8 inches.

Let me clarify.

The brake wires that may need to be extended are at the axles themselves, not at the 7-pin/truck connector. I'm not running all new brake wires.

To extend them I was going to cut the two main wires and splice in a 6" to 1' piece of wire to extend the wires to the brakes on the axles.
